Parallel Generation of Simple Null Graph Models

2020 IEEE International Parallel and Distributed Processing Symposium Workshops (IPDPSW), 2020
The generation of uniformly-random graphs is a key analytic tool for hypothesis testing throughout social network analysis. This work specifically optimizes the generation of large-scale simple uniform random graphs.

On the null spaces of quartic circulant graphs

Discrete Mathematical Chemistry, 2022
A circulant graph is a simple graph whose adjacency matrix can be represented in the form of a circulant matrix, while a nut graph is considered to be a graph whose null space is spanned by a single full vector.

PERFECT COLORING OF CORONA PRODUCT OF CYCLE GRAPH WITH CYCLE, PATH AND NULL GRAPH

Advances in Mathematics: Scientific Journal, 2020
The Perfect chromatic number χ (H) is the least integer needed for the assignment of colors to all elements of the graph H (vertices, edges and regions), so that the coloring is proper. In this paper we obtained perfect chromatic number of corona product

Is the null-graph a pointless concept?

, 1974
The graph with no points and no lines is discussed critically. Arguments for and against its official admittance as a graph are presented. This is accompanied by an extensive survey of the literature. Paradoxical properties of the null-graph are noted. No conclusion is reached.

Constructions of Spectrally Null Constrained Complete Complementary Codes via the Graph of Extended Boolean Functions

IEEE Transactions on Information Theory, 2023
Complete complementary codes (CCCs) have important applications in communication, radar, and information security. In modern communication and radar systems, certain spectrum is reserved or prohibited from transmission, which leads to the so-called ...

On Steinerberger curvature and graph distance matrices

Discrete Mathematics, 2023
Steinerberger proposed a notion of curvature on graphs involving the graph distance matrix (J. Graph Theory, 2023). We show that nonnegative curvature is almost preserved under three graph operations.

Sample size graphs for “proving the null hypothesis”

Controlled Clinical Trials, 1984
Sample size graphs are given for clinical trials designed to test whether an experimental therapy is as effective as a standard therapy. We assume a dichotomous outcome variable and a one-sided test of the hypothesis that the probability of success with standard therapy is greater than the probability of success with experimental therapy by at least ...

Unfolding temporal networks through statistically significant graph evolution rules

International Conference on Data Science and Advanced Analytics, 2023
Understanding and extracting knowledge from temporal networks is crucial to understand their dynamic nature and gain insights into their evolutionary characteristics Existing approaches to network growth often rely on single-parameterized mechanisms ...

Time-Correlated Window-Carrier-Phase-Aided GNSS Positioning Using Factor Graph Optimization for Urban Positioning

IEEE Transactions on Aerospace and Electronic Systems, 2021
This article proposes an improved global navigation satellite system (GNSS) positioning method that explores the time correlation between consecutive epochs of the code and carrier-phase measurements, which significantly increases the robustness against ...
